placing an air purification system in the room;
activating the air purification system;
vacuuming all surfaces of the room with a vacuum cleaner;
vacuuming the HVAC coils;
applying a disinfectant to the HVAC coils;
replacing HVAC filter;
vacuuming at least one HVAC vent;
applying the disinfectant to the at least one HVAC vent;
placing an enzyme tablet in the HVAC condensation drip pan;
applying the disinfectant to all hard surfaces in the room;
applying the disinfectant to all soft surfaces in the room other than carpet;
treating the carpet;
treating room with hydroxyl treatment;
vacuuming the carpet with the vacuum cleaner;
encasing bedding in protectors;
applying a protectant to soft surfaces with a fogger;
applying a protectant to hard surfaces with a cloth;
placing the air purification system for normal usage; and
providing an upright vacuum in the room for occupant usage.

### Claim 2 (depends on 1)

The method according to claim 1 wherein:
the air purification system contains an ionization system, a carbon filter, a HEPA filter, and oxidizers to prevent contamination.

### Claim 3 (depends on 1)

The method according to claim 1 wherein:
the vacuum cleaner contains a HEPA filter.

### Claim 4 (depends on 1)

The method according to claim 1 wherein:
the enzyme tablet contains no tea tree oil.

### Claim 5 (depends on 1)

The method according to claim 1 wherein:
the disinfectant contains no cleaning solutions.

### Claim 6 (depends on 1)

The method according to claim 1 wherein:
the disinfectant is applied to the hard surfaces with a cloth.

### Claim 7 (depends on 1)

The method according to claim 1 wherein:
the disinfectant is applied to soft surfaces with a microsprayer or ULV fogger.

### Claim 8 (depends on 1)

The method according to claim 1 wherein treating the carpet comprises the following steps:
applying crystallizing shampoo to carpet;
applying dust mite and flea control product to carpet;
applying allergen and odor neutralizer to carpet; and
applying disinfectant to carpet.

### Claim 9 (depends on 1)

The method according to claim 1 wherein:
the upright vacuum cleaner contains a HEPA filter.

### Claim 10

A method of providing a room that is both clean and substantially free of allergens, wherein the room comprises at least hard and soft surfaces, carpet, and an HVAC system having coils, a filter, a condensation drip pan and at least one vent, the method comprising:

activating the air purifier system;
vacuuming all surfaces of the room with a vacuum cleaner, the vacuum cleaner including a HEPA filter;
vacuuming the HVAC coils;
applying a cleaning and disinfectant solution to the HVAC coils;
replacing HVAC filter;
vacuuming the at least one HVAC vent;
applying a disinfectant to the at least one HVAC vent, the disinfectant being free of cleaning solution;
placing an enzyme tablet in an HVAC condensation drip pan, the enzyme tablet being free of tea tree oil;
applying the disinfectant with a cloth to all hard surfaces in the room;
applying the disinfectant with a microsprayer or ULV fogger to all soft surfaces in the room other than carpet;
treating the carpet with the following steps:
applying crystallizing shampoo to carpet with a multifunction cleaning device;
applying dust mite and flea control product to carpet;
applying allergen and odor neutralizer to carpet; and
applying the disinfectant to carpet with a microsprayer or ULV fogger;
treating room with hydroxyl treatment;
vacuuming the carpet with the vacuum cleaner;
encasing bedding in protectors;
applying a protectant to soft surfaces with a ULV fogger;
